Hi! I've been using Kenko extension tubes ans received underexposed slides. Now, I thought that TTL will take care of everything -- well, I was wrong.
I found (Kenko site) that I should've used exposure compenstaion and there are stated exposure factors. But what do they mean? For 20 mm ext. tube its. 2.0. Does this mean 2 f stops? And for 56 mm it is 4.5 - 5.0, depending on the focusing distance. Does this mean 4 to 5 f stops? Regards, IVI. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
